Micro-Characterization of Wireless Channels

2004
The previous chapter concentrated on estimation of the mean or median signal strength for a given transmitter and receiver geometry characterized by a certain terrain definition in a coverage area. The concept of statistical signal coverage was also presented.

Characterization of channel-forming peptide nanostructures

Biophysical Chemistry, 2012
We have prepared fluorescent analogs of known ion-channel-forming synthetic peptide nanostructures. These analogs were designed as probes to gain insight about the mechanism by which self-assembling amphiphilic peptides interact with lipid membranes. Conformational studies demonstrated that the labeled analogs retain their propensity to adopt a strong ...

Characterizing spatial correlation in indoor channels

2004 IEEE Wireless Communications and Networking Conference (IEEE Cat. No.04TH8733), 2004
The spatial correlation features of channel impulse responses for an indoor environment are presented. The wide-hand impulse responses of a rectangular enclosure are calculated using the method of images. Bandpass representations of the non line-of-sight multipath responses are obtained for 2.4 GHz ISM band and their spatial cross correlation estimated

Channel characterization using bispectral analysis

Proceedings of the IEEE, 1988
A method of characterizing a slowly varying linear channel in the presence of white Gaussian noise is proposed. The method uses a non-Gaussian probing signal and performs a bispectral analysis of the received signal. >

Identification and characterization of the murine TRPM4 channel

Biochemical and Biophysical Research Communications, 2003
The transient receptor potential (TRP) channels form a superfamily with six transmembrane structures, which is common in other types of voltage-dependent channels. The TRP-melastatin (TRPM) subfamily includes the putative tumor-suppressor melastatin, which was originally found as a down-regulated protein in melanoma tumor cell lines.

Radio Channel Characterization by Three Tones

IEEE Journal on Selected Areas in Communications, 1987
Three radio pilot tones, available on in-service AR6A single sideband radios, have been used to characterize the dispersive nature of radio fading. The paper presents new results on how three tones can be used to determine the delay and amplitude of the second ray and the notch frequency in a two-ray fading model.

Wideband mobile radio channel characterization

Annales Des Télécommunications, 1999
La caracterisation a large bande des canaux radioelectriques est realisee a partir de sondeurs. Ces systemes emettent soit une impulsion, soit une suite pseudo-aleatoire dit prbs (pseudo random binary sequences) et utilisent en reception une technique de compression s’appuyant sur unfiltre adapte ou sur un correlateur.

Channel Characterization for Mobile Satellite Communications

1995
This paper concentrates on channel modelling for mobile personal satellite systems. A single-environment channel model is introduced suitable to quasi-stationary flat-flat channels. The model is compared with results taken from the literature. Also a two-state generative channel model with parameters fitted from measurements is presented.

Characterization for Series-Parallel Channel Graphs

Bell System Technical Journal, 1981
Channel graphs are often used to describe the connecting paths between a pair of terminals in a link system. Series-parallel (SP) channel graphs and Takagi graphs are special classes of channel graphs heavily studied in the literature. In this paper, we give a noninductive definition of SP channel graphs which we prove to be equivalent to the usual ...
